NASA has an interesting article on Spaceweather.com, see link, which is copied and shown below. Key statement: "Our latest measurements show that cosmic rays are intensifying, with an increase of more than 12% since 2015. Why are cosmic rays intensifying? The main reason is the sun. Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return."

"Cosmic Rays in the Atmosphere

Updated: Sept. 29 2016 // Next Flight: Oct. 1, 2016

Sept. 20, 2016: Readers, thank you for your patience while we continue to develop this new section of Spaceweather.com. We've been working to streamline our data reduction, allowing us to post results from balloon flights much more rapidly, and we have developed a new data product, shown here:

This plot displays radiation measurements not only in the stratosphere, but also at aviation altitudes. Dose rates are expressed as multiples of sea level. For instance, we see that boarding a plane that flies at 25,000 feet exposes passengers to dose rates ~10x higher than sea level. At 40,000 feet, the multiplier is closer to 50x. These measurements are made by our usual cosmic ray payload as it passes through aviation altitudes en route to the stratosphere over California.

What is this all about? Approximately once a week, Spaceweather.com and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. These balloons are equipped with radiation sensors that detect cosmic rays, a surprisingly "down to Earth" form of space weather. Cosmic rays can seed clouds, trigger lightning, and penetrate commercial airplanes. Furthermore, there are studies ( #1, #2, #3, #4) linking cosmic rays with cardiac arrhythmias and sudden cardiac death in the general population. Our latest measurements show that cosmic rays are intensifying, with an increase of more than 12% since 2015:

Why are cosmic rays intensifying? The main reason is the sun. Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. (bold added) Another reason could be the weakening of Earth's magnetic field, which helps protect us from deep-space radiation.

The data points in the graph above correspond to the peak of the Reneger-Pfotzer maximum, which lies about 67,000 feet above central California. When cosmic rays crash into Earth's atmosphere, they produce a spray of secondary particles that is most intense at the entrance to the stratosphere. Physicists Eric Reneger and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today."

Sowell comments:

The mainstream climate community, especially the IPCC, claims that man-made carbon dioxide (CO2) is responsible for the average climate warming over the past 100 years. Especially, they make that claim for the last 25 years of the 20th century, from 1975 to 2000. Since 2000, however, the warming has stopped, a feature that is known as "The Pause." What is known now, from experiments in the CERN cloud chamber, is that cosmic rays do in fact cause clouds to form, and the sun's magnetic field weakens as the sunspot numbers decrease.

Given the much weaker sunspot cycle presently, cycle 24, it is no surprise then that the Earth is cooling as more cosmic rays strike the atmosphere and produce more clouds. It does not take much more cloud cover to change the precarious balance between slight warming and cooling.

The data from above shows a 12 percent radiation increase in only 18 months.

Subtitle: St. Lucie Nuclear Plant Unreliable in a HurricaneThe recent flap in Australia that saw the state of South Australia suffer a grid blackout due to high winds prompted a storm of controversy over whether or not wind power, a renewable energy source, was to blame. Of course, many of the anti-renewable crowd advocated for more nuclear power plants, saying they are reliable where wind power is not. The irony is that here, half a world away in Florida, hurricane Matthew forced the St. Lucie nuclear power plant to shut down. The story was given as: "St. Lucie Power Plant shut down because of Hurricane Matthew" -- see link to TCPalm.com story 10/7/2016. From the article: "Federal rules require nuclear plants to be shut down at least one hour before hurricane winds hit the site, spokesman Peter Robbins said. FPL closed the Hutchinson Island plant at 11:15 a.m. and will reopen it after the category 4 storm is over. Its reopening might be delayed if access roads are blocked because rules require an evacuation route for a power plant to remain open, he said." (note: FPL is Florida Power and Light; the St. Lucie nuclear plant is located on Hutchinson Island just south of Vero Beach, Florida)For background, Hurricane Matthew was a category 4 that traveled northward as it remained offshore but brushed the entire eastern seaboard of Florida from October 5 through October 8, 2016. Hurricane winds are sustained wind of 75 miles per hour or greater. Wind speeds reported by the National Weather Service at Vero Beach, just 10 miles north of the St. Lucie nuclear plant, showed maximum sustained winds of 49 miles per hour at 3:53 a.m. on October 7, 2016. Winds gradually increased to that point, then decreased steadily after. Wind gusts were higher, as expected, with the highest at 74 miles per hour. It is also noteworthy that Florida reported more than 1 million customers lost power due to hurricane Matthew's winds. Those were most likely the low-voltage lines, and not the high-voltage backbone of the grid. This is crucial because an offline nuclear power plant consumes a great deal of electricity to run cooling systems and other critical systems to prevent a meltdown. St. Lucie also has, by law, backup generation capability to supply power for a few hours when the grid cannot. The controversy over wind power continues. It is clear, though, that nuclear power plants are not quite as reliable as the nuclear cheerleaders claim. In this case, no one could know if Hurricane Matthew would veer westward and bring 74-mph and greater winds across St. Lucie nuclear plant. As it turned out, no hurricane winds hit the nuclear plant. Still, shutting it down as a precaution was the correct thing to do. Nuclear plants pose a sufficient danger that it is much better to shut one down in a calm and orderly manner than to have a crash shutdown in the midst of a hurricane. Roger E.

Subtitle: Record-Setting Solar Power Reduces Natural Gas DemandThe peak summer heat is now ended in Southern California, indeed, a winter storm warning was issued for the central Sierra Nevada mountains. One short and fairly mild heat wave occurred last weekend, with temperatures measured at Los Angeles (USC Campus) reaching 104 degrees F for one day. (see adjacent Figure 1). The orange oval shows the period in which heat waves typically occur, this year only twice did temperatures break 100 degrees F. The major conclusion is that zero blackouts occurred, because renewable power from solar PV, solar thermal, and wind turbines produced electricity at rates up to 10,000 MW throughout the summer.

Figure 1 - 2016 year-to-date temperatures at Los Angeles, California

As is well-known, officials have concern that grid instabilities or blackouts would occur this summer during heat waves, because the natural gas storage supply is much reduced due to the Aliso Canyon storage facility being out of operation. However, solar power and wind power need no natural gas, and provided power routinely through the summer. Solar PV actually broke records for power production. The California grid has many efficient, combined-cycle gas turbine power plants with quick response capability to adjust their output when solar or wind output changes suddenly. The state also imports some power from adjacent states, notably nuclear power from Arizona, hydroelectric from Nevada (Hoover Dam), and both wind and hydroelectric from Washington. It is notable that long-distance transmission lines are required to ship the power into California. It is also noteworthy that the adjacent states have surplus power to sell to California and do so profitably. Now that Fall and Winter are here or looming, the gas shortage continues due to Aliso Canyon's problems. However, wind power increases in those seasons, which offsets the declining solar power production. Next year will have even more solar power production as California installs even more PV power plants. The state's renewable energy plan requires approximately 3,000 MW of renewables installed each year. Almost all of that will be solar PV, since wind locations are essentially built out, and solar thermal has much worse economics. Roger E.
